InfraRed (LWIR) Imaging used for fever screening

Teledyne Dalsa Calibir LWIR camera

Long Wave Infra Red (LWIR) cameras have been used for industrial applications to detect infrared light in the 8-14um wavelength region. This infrared light is invisible radiant energy that we experience as heat but can not see.   Applications for LWIR cameras continues to expand past industrial applications now entering into medical markets such as fever screening.

Teledyne Dalsa has expanded the Calibir LWIR camera series introducing the latest Calibir GXM model now with radiometric capabilities. With outbreaks of infectious diseases such as Covid 19, LWIR cameras can be used for fever screening by detecting elevated skin temperatures. Using optics, the cameras provide the ability to take the temperature of individuals keeping save distances between patients and medical practitioners.

All cameras are factory-calibrated for reliable radiometric performance, have outstanding dynamic range and allow the best possible NETD over a vast range of temperature (>600C). . Coupled with many features such as multiple ROI, color maps, LUTs and the ability to sync and trigger multiple cameras, makes the Calbir GXM a good solution for many thermal imaging applications.

Image threshold
Example: Thresholding with Look Up Table (LUT) allows the Calibir GXM to mark certain temperatures with color while leaving the rest in monochrome.

Considerations for Color machine vision cameras using a Bayer filter – White paper

Dalsa Falcon camera

Users of single chip color machine vision cameras have lots of choices in camera features. The following are a few issues relating to these types of cameras that users need to be aware of when they are choosing their camera type.

First, its important to understand how a “single chip” machine vision color camera creates a color image. Thanks to Bryce Bayer of Eastman Kodak, we have the “Bayer” filter mosaic filter pattern that generates a color image through interpolation which is the technique used in most machine vision cameras today.

From a macro view, using the Bayer filter, we collect light onto individual pixels through each of the red, green and blue filters which assigns intensity values. Using various interpolation methods, each pixel uses data from adjacent pixels to determine its color to generate a nice color image.

There are several considerations in color imaging during this process such as:
1 – Bayer conversion – Understanding this is important as it may effect the computer CPU load and image fidelity.
2 – Frame rates – Depending on the color format (ie. RGB vs Raw), you will need to understand how this effects the camera frame rate requirements and camera interfaces.
3 – Color formats – Depending if the application simply wants to identify a blue vs red part vs doing a more in depth color analysis will determine which color format is utilized.

1stVision has published a white paper addressing these considerations in the link below.

Download this comprehensive white paper – “Considerations for Color machine vision cameras using a Bayer filter. Click HERE.

For any color application, there is various color camera technology that needs to be considered first. 3-Chip Color machine vision cameras have advantages over Bayer color cameras in which color fidelity and resolution are superior. Additional resources on each aspect is below:

Color Fidelity – If your application requires high color fidelity and trying to detect small differences in color, 3 chip color cameras should be also considered. Learn more in this related blog HERE.

Resolution – Due to the interpolation in Bayer color cameras, the overall resolution is reduced significantly. In applications where resolution AND color are important, 3 chip color cameras provide these advantages. Comparison images and further explanation can be found in this blog HERE.
